A PSZ3000-B semi-mobile gyratory crushing station, independently designed and manufactured by Luoyang, China-based CITIC Heavy Industries (CITIC HIC) for the second phase expansion project of Zijin Mining’s Duobaoshan copper-molybdenum mine in Heilongjiang Province, recently successfully completed its no-load and load testing, and the OEM says all performance indicators met the design standards.
CITIC HIC says it customised the PSZ3000-B semi-mobile gyratory crushing station, which has a capacity of up to 4,450 t/h, to meet the extremely cold environment and specific needs of the Duobaoshan Phase II expansion project. The crushing station is specifically designed for extremely hard ore conditions, featuring structural reinforcement of the core main unit to significantly improve the safety factor of key components. It also has enhanced load-bearing start-up capability to ensure rapid resumption of production after unexpected shutdowns, effectively guaranteeing operational continuity under extreme conditions.
To handle -40°C extreme cold climate conditions often seen at this mine in winter, the crushing station innovatively adopts a closed insulation device. Through the integrated design of high-performance insulation materials and steel structure, it ensures equipment insulation while also providing insulation for inspection and maintenance personnel.
The crushing plant is also one of the first in China to integrate a vibrating feeder, utilising its high-frequency vibration characteristics to effectively activate material flow and eradicate the persistent problem of material blockage caused by frozen blocks of material.
Adhering to the concept of factory manufacturing and modular assembly, the crushing plant has a modular steel structure system. Each functional module is prefabricated and pre-assembled with high precision in the factory, requiring only efficient combination on-site, significantly reducing the outdoor construction period in high-altitude and cold regions.
The successful implementation of this project CITIC HIC is part of its focus on moving from being primarily a supplier of crusher products to a supplier of comprehensive crushing systems integrating design, manufacturing, transportation, installation, and commissioning.
It says the new crushing station will also strongly promote the efficient, energy-saving, and green development of the Duobaoshan mine and enhance its overall performance. CITIC HIC says it possesses many years of experience in the design and manufacturing of semi-mobile gyratory crushing plants and has set many industry standards in this field.
It says it can flexibly equip its plants with hydraulic gyratory crushers and auxiliary equipment of appropriate specifications according to customer needs, achieving a high degree of customisation in its designs. The crushing plant processing capacity ranges from 1,500t/h to 15,000t/h, and it adds that the performance reaches the same level as top international brands.
Previously, CITIC HIC had provided semi-mobile gyratory crushing plants of various specifications for projects such as the Letpadaung copper mine in Myanmar, LKAB’s Svappavaara iron ore operations in Sweden, the Deziwa copper-cobalt mine of China Nonferrous Metals Industry Corporation, and the KFM Phase II crushing plant for Luoyang Molybdenum Group. It says these plants meet the most stringent international standards and have some of the highest efficiencies in the industry, plus longevity with some of them already passing 12 years or operation.
